Materials Data on La2Bi by Materials Project
La2Bi crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent La sites. In the first La site, La is bonded in a 4-coordinate geometry to four equivalent Bi atoms. All La–Bi bond lengths are 3.49 Å. In the second La site, La is bonded to five equivalent Bi atoms to form a mixture of distorted corner and edge-sharing LaBi5 square pyramids. There are one shorter (3.40 Å) and four longer (3.43 Å) La–Bi bond lengths. Bi is bonded in a 9-coordinate geometry to nine La atoms.
